The entire list of gloxinia diseases listed below must be detected in time and started to fight.

In order to grow gloxinia, you need to familiarize yourself in more detail with those diseases that may arise in the process of growing this plant.

The main difficulties are pests and diseases that gloxinia is susceptible to. In the article, we will consider in more detail the types of possible plant diseases and methods of dealing with them. And also what measures need to be taken to prevent gloxinia diseases, and in what conditions to grow a healthy flower.

Structure and features

Gloxinia leaves are large enough, up to 20 centimeters, oval, dark green, velvety. They form a rosette on a short, thick stem. In synningia, the standard leaf position is horizontal. Sometimes on the leaves there are streaks of a silvery tint. The underside of the leaf is reddish or light green.

In shape, they resemble an elongated, oblong heart. Their size is small, and the surface is fleecy. The leaves of this plant are wide, but pointed at the tip. Together with picturesque flowers, an extravagant and interesting union is obtained.

Types of diseases and their photos

Brown spots

The appearance of brown spots on gloxinia indicates diseases such as anthracnose or ascochitis.

Anthracnose

A fungal disease, the signs of which can only be seen if there are brown spots on the surface of the leaves. Gradually, they begin to attack the shoots and trunk of the entire plant, which leads to their rotting and death. The reasons for the appearance of anthractosis in gloxinia are damage or the presence of improper care.

Attention! Such a fungus is transferred with the help of pests, inventory or precipitation. To eliminate the spread of the disease on other plants, they should be treated with a fungicide 3-4 times at intervals of several weeks.

Prevention: it is necessary to spray with drugs: oxych, cuproxate, copper chloroxide. After using tools, they must be disinfected immediately in order to prevent further infection.

Ascochitosis

Fungal disease, the signs of which can also be seen only in the presence of red or brown spots with brown edging on the leaves. The main reason for this disease is high humidity in the room.

To save gloxinia from ascochitis, you need:

  1. Remove affected leaves immediately.
  2. Then you need to spray the synningia with Bordeaux mixture, copper sulfate or such fungicides: Vectra, Abigapik.
  3. After a week, repeat the procedure.

Wither

Gloxinia leaves wither with a plant disease such as fusarium. Due to a lack of water and high humidity, a plant can develop such an ailment.

Important! Fusarium is a fungal disease that gets on a flower through an infected substrate. The leaves gradually begin to wither, curl and acquire a pale brown tint.

  1. To combat this ailment, gloxinia should be removed from the pot and freed from the soil.
  2. Then treat with fungicides: Topaz and Fudnazol.
  3. And at the very end, the plant must be planted in new soil.

Why curl?

Consider why Gloxinia leaves curl. This is due to the wrong irrigation system. If the plant receives too much water, then its leaves begin to curl in the form of a so-called spoon. Watering can be a way to combat this disease. Before the next watering, be sure to dry the top layer of the soil. One more the reason the leaves curl up is insufficient air humidity or too high a temperature. Then it is necessary to put a vessel with wet expanded clay near the pot and reduce the air temperature.

Turn yellow

Chlorosis

A disease that occurs with low acidity of the soil, which is a consequence of watering the plant with too hard water (what kind of soil is needed for gloxinia?). You can determine the disease by external signs by the yellow spots on the leaves of gloxinia.

For your information: To cure a plant, it must be transplanted and irrigated only with soft, warm water. For transplanting, you need to take a light and sour substrate that can allow air to pass to the root system of the plant.

Rusty mushroom

In the event that bubbles of various colors appear inside the gloxinia leaf, it is possible to speak with accuracy about this plant disease. The reason for its appearance may be insufficiently good care, keeping in a damp and too cold room (read about the features of growing gloxinia and caring for it here). In order to combat this disease, it is necessary to remove all damaged parts of the flower and provide high-quality care for the "tropicana". For prevention, spraying with colloidal sulfur should be carried out.

Turn black

The cause of this ailment may be the appearance of gray rot. The causative agent of the parasite of blackness can be the increased humidity of the soil in the pot.

To treat a plant you need:

  1. Remove the bush and examine it carefully.
  2. If there are damaged parts of the tuber and aerial elements, then remove them.
  3. Treat the remaining healthy parts with Topaz or Fundazol.
  4. Then you should transplant the recovered plant into new high-quality soil (read how to transplant gloxinia and how to grow it here).

Brown dots

Ugly brown dry spots can be caused by gray mold. You can cure such a disease as follows: cut off the infected areas of gloxinia and treat the entire plant with a fungicide. Another reason for the appearance of such spots can be sunburn, which occurs on the leaves of the plant when it is in the bright rays of the sun. Leaves also develop brown specks if they get too much water.

It is imperative to water the flower very carefully, along the edge of the pot. Such characteristic spots also indicate plant diseases such as thrips, which leave brown spots in the form of a fine mesh. You can cure a plant from thrips as follows: watering and spraying with Actellik, after 10 days you need to repeat the procedure, the treatment should be carried out 2-3 times.

Dry

If the leaves of gloxinia began to dry, especially the lower ones, then the reasons may be such factors as insufficient air humidity or flooding with water. To eliminate this ailment, it is necessary to carry out treatment with Fungicide or Fitosporin.

What to do for prevention?

For, in order to prevent various leaf lesions in gloxinia, it is always necessary to carry out prevention.

  • Firstly, irrigation should be carried out on time when the plant itself needs it. In this case, there will be no overdrying and soil flooding.
  • Secondly, do not place the plant where the bright rays of the sun fall on it.
  • Thirdly, before planting gloxinia tubers in the ground, they should be pre-processed.
  • And, fourthly, it is necessary to monitor the humidity in the room where the flower is located.

Prerequisites for Healthy Growth

For good growth of synningia, the following conditions must be observed:

  1. Gloxinia pots should not be too close to each other.

    It is necessary to ensure that the flowers do not touch each other with leaves. If there is not enough space, the flower can stretch out.

  2. Light and sound soil, timely fertilization of the soil.

    In this case, it is best to choose a peat-based soil. Top dressing needs to be applied several times a month, but preferably no more than three (read about how to properly water and feed gloxinia in our material). Potassium monophosphate or Fertika Lux should be used.

  3. The temperature should be between 18-25 degrees.

    If the temperature is too low, then the development of gloxinia will stop, and at high, on the contrary, the flowers do not open well, the plant loses the turgor of the leaves (you can find out why the buds turn black, dry, rot and do not open here).

  4. Good lighting, which should be diffused and bright.

    You need to put the plant on the windowsill so that it faces east or west. The daylight hours should last 12-14 hours.

  5. Timely soil moisture.

    Between irrigations, the top layer of the soil should have time to dry out a little. Watering should be done through the pallet or along the edge of the pot. Only room temperature water can be used. After moistening, excess water should go through the holes in the pot (you can find out what kind of pot you need for gloxinia here).

Conclusion

The list of the above diseases that occur in gloxinia is not exhaustive. In this case, in order to prevent the death of the plant, it is necessary to detect the disease in time and begin an active fight against it. If all preventive measures and the very fight against the disease are not carried out in a timely manner, then you can lose not only this plant, but also the neighboring ones. The best option in this case is to provide conditions suitable for the development of gloxinia, and timely prevent possible diseases.
